6. These tires are simply amazing! No increase in road noise; accelerating traction, braking traction, and cornering traction are dramatically increased in both wet and dry. I've almost lost control multiple times with the previous RE92s, but with these F1s, i can seriously drive around and take corners a lot harder with 5 times more confidence Plus before i got the amazing deal on these tires, i wanted to do a brake upgrade (SS Lines, pads, and fluid).. but with these tires, it turned the "need" into a "want". Probably one of the best modifications
